The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the …

1 Wash, filter, and grind the granite ore into smaller pieces. 2 Put the ground ore into a tank containing a dilute cyanide solution and add zinc. The chemical reaction between a dilute cyanide solution and zinc will separate the gold from the ore. 3 Use a filter press to remove the gold from the solution.

The results of the stage test showed that it is advisable to use a two-stage scheme for ore processing. The first stage of concentration in the grinding cycle (ore size 60–70%– 0.071 mm), the second at the final size (80%–0.071 mm). According to the GRG test, the ore is efficiently con-centrated by centrifugal methods.

Variation of ore crushed in 2012 (wmt – wet metric tonne) The most important factor is that, if the ore is clean, excluding non-ore materials and its brittleness is high, the ore is being crushed in a quicker and easier way without causing any problem. More fragile particles are easily broken into smaller particles.

Crushed ore agglomeration. Crushed ore agglomeration has two major aims. First, it is the best opportunity for the thorough application of the leaching solution prior to building the heap and "kick starting" the leaching process itself (Bouffard, 2005, Dhawan et al., 2012a, Kodali et al., 2011a, Purkiss and Anthony, 2004).
